WebFeb 29, 2024 · This shows that binding of the Sm 7 protein complex to telomerase RNA, in addition to providing stability, dictates formation of the mature end of the poly(A)– isoform just 3′ of its binding site, and that TLC1 processing proceeds in a 3′-to-5′ manner, likely through exonucleolytic trimming as was proposed previously. WebThe major cleavage at site A3 in ITS1 followed by exonucleolytic digestion to site B1, together with the alternative pathway via direct cleavage at site B1, generate two mature 5′ ends of 5.8S rRNA, whereas cleavage at site C2 accompanied by exonucleolytic trimming produces the mature 5′ end of 25S rRNA.
